The Fig. 10 is a transverse section.of a portion of enlargement at the bottom of the insert serves 55 to anchor the insert in the cement without the aid of additional fastening devices.

The upper end plates 4 of each of the sections are connected together by angle iron plates 10 which extend around the entire structure, as shown in Fig. l in which the plates are shown partly in full lines and partly in dotted lines. In a four-sided structure four of these plates would be employed, the adjacent ends of which are connected together by angular straps I 1 preferably riveted thereto. The saidheadplates 4 of th'e respective wall; sections are connected to-these plates I by bolts l2 (Figs. 1, 2 and 9) The end walls 2 of'adjacent sections are each formed with a V-shaped depression (3, which when pressed together form a vertical rectangular groove in which is inserted a suitable plastic material I4 to provide for calking and also furnish an expansion joint between adjacent sections. The end walls tions are also interlocked by providing the inner edge of one end wall with a lateral flange l5 and the adjacent end wall with a lateral'flange IS, the edge of the flange l5 being bent to hook form as indicated at l5 so as to receive a hook l6 formed on the edge of the flange l6.

To interlock these flanges,'-after' one section has been properly positioned an adjacent section is held at a slight angle thereto so that the hook I 5' may be engaged with the hook l6 after which the succeeding section may be swung parallel with the first section.

Located in each of the side wall sections is a plank of insulating material l1. Each of these planks of insulating material is centrally positioned in its corresponding side wall sections and is held in position by providing the side edges thereof with V-shaped grooves which receive the V shaped depressions l3 of the ends 2 of the side wall sections. These insulating planks may be of any suitable material such as flber impregnated with pitch and termite-proof'compound and the outside surface is covered with a sheet 18 of aluminum, copper or other reflective type of insulation to add toits insulating value.

Each of the side wall sections is provided with means for draining the condensation on the inside thereof and for a circulation of air between the wall "I and'theinsulationg, Referring to Figs. 15, 16 and 17, the lower: end of each side wall section at the point where the wall I joins with the base plate 3 is depressedto form a drain trough 19 having an opening 20. This opening 20 not only permits the escape of the condensation but also permits the entrance of air which will circulate upwardly-an'cl' escapethrough an opening 2| in the head plate 4.

The floor joists for'the structure are best shown in Figs. 8 and13. Each joist is formed of sheet metal and consists of-a flat central .web portion 22 having mounted on one edge thereof a flange 23 which is received in a channel of the adjacent joinst consisting of *a flange 24 having its edge provided .with a Ubend 25.

" There is provided a seriesof roof joists which are constructed in all respects like the floor joistsexcepting that they are inverted (Figs. 1, 2 and 9). The horizontal portion of these joists is indicated at 26; having one edge thereof formed with an upwardly'turned flange 21 and the other edge with an upwardly turned U-bend 28 which receives the flange 21 of the adjacent joists. These roof joists are secured to the angle iron plates ID by the same bolts l2 which secure -cent ends thereof a sheet 2 of adjacent side wallsec-- the rafters and is slit to the side wall sections and the plates together, these bolts passing through the horizontal portions 26 of the joists.

A series of roof rafters are employed, these rafters being shown 14. Each of these best in Figs. 1, 2, 9, 12 and rafters is formed of sheet metal consisting of a flat web portion 28 having a flange 30 on one edge which fits in a U-bend 3! on the edge of the adjacent rafter.

The flanges and U-bends of the rafters occupy "positions-between the flanges andU- bends of the floor joists and tie rods '32- pass through the flanges and U-bends 01' both the rafters and joists to anchor the rafters in position, these tie on their ends to clamp against the flanges of the outermost joist.

,' Tosecure :the upper adjacent ends of the rafterstogether there is inserted between adjametal strip 33 (Figs. 12 and 14) the upper edge of which projects beyond v form tongues 33' which are alternately bent in opposite directionsand secured to the rafters by nails 34 .or other suitable fastening devices.

The "roofing sections are formed of a base or sheathing 3 5 preferably of the same material as that of the insulating strips l1. A sheet of copper 36 is glued on' the upper side of each section 35 with the sheets at adjacent edges of the sections 35 projecting beyond the sections so that they can be upturned in parallel relation as indicated at 36' in Fig. 11 and secured together by U-shaped clips 31 and rivets 38 (see also Fig. 9). The insulated sheathing material '35 is applied to the stallation. Atthepoint where a'window is to be installed the side wall sections indicatedat Ila are short so or more of thejshort side wall sections. I In installing the windows the lower short sec,-

tions are erected, these sections being constructed the same in all respects as the ,side wall sections previously describedwith' the exception thatthe upper hea fjplate, fisl omitted. A metallic sill 42 is placed over the lower short s e wall section, a portion. of this sill preferablyjresting on a wooden strip"43 which" is supported by the top of the '"short"lowei wall sections The window constructed in the same manner as the long sections previously described with the ex'ception that the lower base-.plateyfl'. =is formed with a longitudinally extending groove 45 -toreceive calking material 46 into which the vertical flange of the upper portion of the window of the frame 'is placed, calking material having also been. placed in the pocket formed by the angular frame. The

vertical flanges of the sides of the window frame are imbedded in the plastic N in the V-shaped grooves of the adjacent full-height side wall sections I as shown at the top of Fig. 3.

For the corner joints between the side wall sections the sections at the ends of the structure are slightly modified, as shown in Fig. 3, so that the vertical ends 2' of adjacent corner sections will be angularly arranged and the shape of the depression I3 altered so as to provide a triangular shaped groove instead of a rectangular In erection one of these corner sections groove. is first placed in position and bolted to the foundation. in the manner previously described by the bolts 5. The other corner section is turned at such an angle to the first section that its interlocking flange may be interlocked with the interlocking flange of the first section and then turned to its proper position, the flanges hinging upon each other. When this last section reaches its flnal position parallel with the wall the joints are interlocked perfectly tight and are ready to receive its securing bolts 5.

In Fig. 10 there is shown the manner of securing the door frame to one of the vertical ends 2 of a side wall section. In this case the interlocking flange on the end 2 is omitted and there is bolted to the outer surface of the end 2 a slip 41 by bolts, one of which is shown at 48. This slip has a V-shaped depression 49 which cooperates with the vertical depression i3 of the side wall section to provide a groove for calking compound 50. It also has its side edges downturned as indicated at 5| and 52 to provide grooves to receive the inturned edges of substantially U-shaped door frames 53.

The interior finish consists of sheets of ply wood 56 which are nailed to wooden strips 55, two only of which are shown inFig. 3. These wooden-strips are secured to the ends 2 of the side wall sections by screws or other suitable fastening devices. About all window frames and door frames a metallic clip trim 56 is employed,

the details of which need not be described as" these trims are stock articles now on the market.

In Figs. 4 and 5 there is shown an arrangement for providing a partition in the structure. U shaped spacing channels 51 and 56 are secured respectively to the ceiling joists and floor joists and are of a-length equal to the desired length of the partition. These channel members are secured to the joists by clincher nails as shown. A series of studs 59 built up of two sheet metal channels riveted together are positioned between the channels. After the channel members are in place the studs merely set in position on the inside of the channel member; 'An interior finish 60 of ply board is secured to the studs by means of steel clinching nails driven between the two members of the stud, theupper and lower edges of the ply board finish resting against the webs of the steel channel so as to keep them properly alined.

For a two-story structure the side wall sections are made twice as high as for a one-story structure and means are provided to have these side wall sections support the ceiling joists for the first story as shown in Figs. 6 and 7. To this end a beam 6| is extended longitudinally through the ends 2 of the side wall section, the

ends being provided with slotted openings 62 to receive the beam. Upon this beam rests the ceiling joist, a portion of one of which is indicated at 63, one of these beams being located upon each side of the structure. The lower edges of the joists have recesses 64 to receive the beams. These joists are constructed in all respects like the ceiling joists heretofore described with flanges and U-bends, these flanges and U- bends being the part which rests upon the beam.

In Fig. 9 there is shown a sheet metal gutter 65, the inner wall 65'. of which covers the open space between the side wall sections and the roof. This inner wall has a bent flange 65" which is inserted between the roof and the roof rafters and braces 66 connect the inner wall 65' with the outer wall of the gutter.
